Q78 2021, Profit, Loss and Discount

If the price of an article is decreased by 20% and then the new price is increased by 25%, then what is the net change in the price?

यदि किसी वस्तु के मूल्य में 20% हास होता है और फिर नए मूल्य में 25% वृद्धि होती है, तो मूल्य में नेट परिवर्तन कितना हुआ है ?

Explanation Please wait..

Let the initial price be Rs. 100.

New price on decreasing the original price by 20% = 100 – 20% of 100 = 100 – 20 = Rs. 80.

Now, the final price on increasing the previous price by 25% = 80 + 25% of 80 = 80 + 20 = Rs. 100.

So, there is no net change in price.
